Campbell was diagnosed with Alzheimer’s Disease in 2011, and subsequently announced a farewell tour for 2011 and 2012. After the tour is when Adiós was recorded to “[capture] what magic was left” according to Glen’s wife Kim. The album features songs that Campbell loved, but never had a chance to record in his career.
As simply as I can put it, making the case that spoken word and rapping in music are the same thing is an ignorance-based insult to the artistic integrity and creativity of both spoken word and rap artists, and to the intelligence of anyone who that case is being made to. Battling the infiltration of country rap is hard enough without revising history.
